Patent number: 8139217Abstract: An alignment system for a lithographic apparatus has a source of alignment radiation; a detection system that has a first detector channel and a second detector channel; and a position determining unit in communication with the detection system. The position determining unit is constructed to process information from said first and second detector channels in a combination to determine a position of an alignment mark on a work piece, the combination taking into account a manufacturing process of the work piece. A lithographic apparatus has the above mentioned alignment system. Methods of alignment and manufacturing devices with a lithographic apparatus use the above alignment system and lithographic apparatus, respectively.Type: GrantFiled: December 23, 2010Date of Patent: March 20, 2012Assignee: ASML Netherlands B.V.Inventors: Franciscus Bernardus Maria Van Bilsen, Jacobus Burghoorn, Richard Johannes Franciscus Van Haren, Paul Christiaan Hinnen, Hermanus Gerardus Van Horssen, Jeroen Huijbregtse, Andre Bernardus Jeunink, Henry Megens, Ramon Navarro Y Koren, Hoite Pieter Theodoor Tolsma, Hubertus Johannes Gertrudus Simons, Johny Rutger Schuurhuis, Sicco Ian Schets, Brian Young Bok Lee, Allan Reuben Dunbar

Patent number: 7565219Abstract: A method according to one embodiment of the invention relates to determining at least one parameter of a model that provides information about a position of an object. The object has a plurality of alignment marks of which desired positions are known. The method includes measuring a plurality of positional parameters for each alignment mark. Based on the measured plurality of positional parameters, which are weighted with weighing coefficients, at least one parameter of the model of the object is determined. The numerical value of each weighing coefficient is determined together with the at least one parameter of the model.Type: GrantFiled: December 9, 2003Date of Patent: July 21, 2009Assignee: ASML Netherlands B.V.Inventors: Maurits Van Der Schaar, Jeroen Huijbregstse, Sicco Ian Schets, Bart Luc Swinnen

Patent number: 7288779Abstract: A method for optimizing an alignment condition of a lithographic projection apparatus. This method comprises projecting a beam of radiation on a target portion of a substrate and measuring a plurality of diffracted signals emitted by the target portion. This method further comprises calculating a variance for each of the plurality of diffracted signals, such that a plurality of variances of the diffracted signals is determined, and adjusting the alignment condition of the lithographic projection apparatus based on analysis of the plurality of variances.Type: GrantFiled: December 17, 2003Date of Patent: October 30, 2007Assignee: ASML Netherlands B.V.Inventors: Sicco Ian Schets, Jeroen Huijbregstse, Allan Reuben Dunbar, Nicolaas Petrus Van Der Aa
